Augh! It's a perfectly cromulant punctuation mark!

Ellora's Cave does not take colons in their work.

But how the flaming Sea am I supposed to punctuate this sentence WITHOUT one?
“At the end, let only this be said: that all Ruvane Delkroy did, he did for love of Etarin.”

To quote the Style manual:

Colon
A colon is rarely used in informal fiction. In most cases, an em dash or a comma will ensure clarity.

See, that to me doesn't say "No colons EVER!" It says "avoid where possible."
